Full priced games to only stream play, no ownership at all kinda suck. Haha. Most people will likely stick to consoles? Unless you really need high accessibility, for e.g. people who travel a lot due to work etc.
consoles will also be going the streaming path next gen.
there's already a
disc-less xbox.
and stadia is not the only streaming service. just the only one daring and big enough to make an announcement at E3 because they own cloud servers world wide.

and if you think about it, to these corporations: physical discs means several things:
they have to pay money to manufacture the disc
pay money to ship the discs world wide
pay money to store (either at the factory or shipping containment / distribution centre), technically lose money if the goods are still in factory idling.
pay money to the middle-man to sell for them (all your gamestop, EBgames, mom-pop gaming stores have nearly died due to online purchasing)
so naturally to these corporations they would be thinking: why not cut all that added overhead and cost and earn it directly with the developers?
and they will sell it as 'meeting the needs of digital natives', aka younger generation.
so chances are within the next 5 years, i'd say game streaming services (just like Netflix) will take off, and we may see more launch titles go digital only (most of the successful indies are already cutting out the middle man). All google did was fired the starting gun early, because even if Stadia fails on their platform, streaming service will still need cloud servers, and there's not many players in that industry, either way google will benefit. behind that would be MS with their Azure and Amazon with AWS and maybe Alibaba cloud.
And concerning ownership: you might want to read the accompanying EULA to your favorite game. chances are, we (even myself) don't legally own the any game. even if it is physical.
